Open Studio for Data Quality

You can move a database connection to the Studio recycle bin whether it is used by analyses or not.

Before you begin

A database connection is created in Talend Studio. For further information, see Connecting to a database.


  1. In the DQ Repository tree view, expand Metadata > DB Connections.
  2. Right-click a database connection and select Delete in the contextual menu.

    The database connection is moved to the Recycle Bin.

    You can still run the analyses that use the connection in the recycle bin. However, an alert message will be displayed next to the connection name in the analysis editor.

  3. To delete the connection from the Recycle Bin, do the following:
    1. Right-click the connection and select Delete.

      When the connection is not used by any analysis in the current Studio, a confirmation dialog box is displayed.

    2. Click Yes to delete the connection.
    3. When the connection is used by one or more analyses in the Studio, the Cannot delete this resource dialog box is displayed to list these analyses:
    • To delete the connection and the analyses, select Force to delete all dependencies and click OK.
    • To keep the connection and the analyses, click OK.
